In a stunning escalation of the Trump administration’s crackdown on pro-Palestinian activism, Immigration and Customs Enforcement (ICE) arrested Mahmoud Khalil, a Columbia student, graduate and green card holder, over the weekend. Khalil, a prominent leader in campus protests against the Israel-Hamas war, was detained in what appears to be one of the first high-profile arrests targeting a student activist under President Trump’s recent executive order.
The arrest has sparked outrage among immigration advocates, academics, and free speech proponents, who argue that the move represents a dangerous politicization of immigration enforcement. Khalil, an Algerian national of Palestinian descent, is a lawful permanent resident, raising questions about the legality and motivation behind his detention.

A Green Card Holder Targeted: The Arrest of Mahmoud Khalil
According to Khalil’s attorney, Amy Greer, ICE officers arrested Khalil in the lobby of his university-owned apartment in New York City. Initially, agents claimed his student visa had been canceled, but Khalil is not on a visa—he holds a green card, granting him legal permanent residency. When his wife retrieved his green card, officers allegedly stated that his residency status had been revoked.
“I demanded to see a warrant, but the agent hung up on me,” Greer told NPR. “Mr. Khalil was under the impression that as a lawful permanent resident, he had some modicum of protection. That clearly isn’t the case.”
Khalil was later transferred to a detention facility in Louisiana, leaving his pregnant wife and legal team scrambling for answers. Greer called the arrest “a clear escalation” of the administration’s threats to deport individuals involved in pro-Palestinian activism.

Trump’s Executive Order and the Alleged Link to Hamas
The arrest aligns with President Trump’s recent executive order targeting antisemitism on college campuses, which directs federal agencies to use all available tools to punish individuals who “endorse or espouse terrorist activity.” A spokesperson for the Department of Homeland Security (DHS), Tricia McLaughlin, stated that Khalil was arrested for “leading activities aligned to Hamas,” a designated terrorist organization. However, no evidence has been provided to substantiate these claims.
Secretary of State Marco Rubio echoed the administration’s stance on social media, writing,
“We will be revoking the visas and/or green cards of Hamas supporters in America so they can be deported.”
Critics argue that the administration is using broad and unsubstantiated accusations to silence dissent.

Columbia University Reacts
Columbia University confirmed reports of ICE officers near campus but emphasized that it “has and will continue to follow the law.” In a statement, the university noted that law enforcement must present a judicial warrant to enter non-public areas of the campus. The arrest has sent shockwaves through the academic community, with many questioning the implications for free speech and the safety of international students.
Michael Thaddeus, a mathematics professor at Columbia, called the arrest “horrifying and unexpected,” noting that targeting a green card holder represents a significant shift in immigration enforcement strategy.
“It means that the strategy of the immigration police has gone in an unexpected direction,” he said.

Legal Battles and the Burden of Proof
Revoking a green card is a complex legal process that typically requires evidence of fraud or criminal activity. Kelli Stump, president of the American Immigration Lawyers Association, explained that only an immigration judge can revoke lawful permanent residency.
“The government bears the burden of proving the reason this person is deportable,” Stump said. “That’s where the fight ensues.”
Greer, Khalil’s attorney, vowed to vigorously defend his rights in court, calling the arrest “a terrible and inexcusable—and calculated—wrong.”

A Broader Pattern of Immigration Crackdowns
Khalil’s arrest is part of a broader pattern of the Trump administration’s efforts to strip immigration status from individuals who fall out of favor with its policies. During his first term, Trump established a task force to review naturalization cases for potential fraud and created a Justice Department unit focused on denaturalization. While the administration has framed these actions as necessary for national security, critics argue they are politically motivated and disproportionately target marginalized communities.

Protests and Calls for Justice
Following Khalil’s arrest, several groups organized rallies in Manhattan to protest what they see as an attack on free speech and due process. Immigrant rights advocates warn that the administration’s actions could have a chilling effect on international students and activists.
“This has the appearance of a retaliatory action against someone who expressed an opinion the Trump administration didn’t like,”
-said Camille Mackler, founder of Immigrant ARC, a coalition of legal service providers in New York.
